Spring AMQP项目什么都不做

Question

我已经为这项任务奋斗了好几天，所以我决定在这里问一个问题。

好吧，我有一个远程RabbitMQ服务器，并且只具有发送和接收消息的权限。 这意味着我无法创建任何东西。

因此，我想接收和/或发送消息。 但是由于某些原因我无法做到。 该应用程序启动，通道创建，bean初始化等。但是接收方和发送方根本不执行任何操作。

我几乎可以肯定，问题很简单，我会在回答后认为我是个白痴，但现在我被困住了。

代码如下。 主要类是标准类，没有任何更改。

ConfigurationClass：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class TestConfiguration {

    @Bean
    public Sender sender() {
        return new Sender();
    }

    @Bean
    public Receiver receiver() {
        return new Receiver();
    }
}

发件人：

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;

public class Sender {

    @Autowired
    private RabbitTemplate template;

    @Scheduled(fixedDelay = 1000, initialDelay = 500)
    public void send() {
        String message = "Hello World!";
        this.template.convertAndSend("ExchangeName","RoutingKey", message);
        System.out.println(" [x] Sent '" + message + "'");
    }
}

接收器：

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;

@RabbitListener(queues = "QueueName")
public class Receiver {

    @RabbitHandler
    public void receive(String in) {
        System.out.println(" [x] Received '" + in + "'");
    }
}

application.properties：

spring.rabbitmq.host=host.com
spring.rabbitmq.port=5673
spring.rabbitmq.username=username
spring.rabbitmq.password=password
spring.rabbitmq.ssl.enabled=true

然后什么也没有发生。 问题是我在做什么错，为什么它不能按我的意愿工作以及如何解决？

我了解复制粘贴整个项目并要求解决我的所有问题并不是一个很好的做法，对此我感到很抱歉，但是目前我看不到任何使我的代码正常工作的方法。 我将很高兴获得任何帮助。

Answer 1

为了能够使用@Scheduled批注，必须首先使用@EnableScheduling启用计划。

尝试将其添加到配置类中：

@Configuration
@EnableScheduling
public class TestConfiguration { ... }

解决此问题后，您可能还需要查看wargre的评论。
